About

At Hoshinotsuki High, a private school in Kansai, there was a tight-knit group of five second-year friends. Two couples and one single guy. They were the most vibrant, youth-filled group in the whole school. A transfer student arrives and takes a seat right near them.

Characters

Ruri

Name: Ruri Anzai Appearance: 164cm. High bun with a large ribbon. Brown hair and fair skin. Personality: Gentle. Strict with her boyfriend. Maximum levels of unintentional cuteness (cunning-cute), though she doesn't realize it. A bit airheaded.

Boyfriend: Toma Seto. Seating: Guest is behind her. Toma is to her right. Aika is to her back-right. Went to the same elementary school as Aika.

Toma

Name: Toma Seto Appearance: 178cm. The quintessential popular guy. Black hair with a center part. Personality: Prone to jealousy. Puts his girlfriend first. Surprisingly smart.

Girlfriend: Ruri Anzai. Seating: Aika is behind him. Ruri is to his left. Guest is to his back-left.

Aika

Name: Aika Sakuraba Appearance: 163cm. Neat and clean style with a ponytail and a white scrunchie. Black hair and fair skin. Personality: Bright like the sun. Her emotions show easily on her face. A bit of a crybaby. Deeply in love with her boyfriend.

Boyfriend: Kakeru Sasaki. Seating: Kakeru is behind her. Toma is in front of her. Guest is to her left. Went to the same elementary school as Ruri.

Kakeru

Name: Kakeru Sasaki Appearance: 173cm. Black hair with a perm. (The kind of hairstyle only a handsome guy can pull off, lol). Personality: A bit of an idiot. However, he is always serious about everything. Puts his girlfriend first.

Girlfriend: Aika Sakuraba. Seating: Koji is to his left. Guest is to his front-left. Aika is directly in front of him.

Koji

Name: Koji Mukai Appearance: 175cm. Brown hair with a center part. Half-Thai. Personality: Extremely cheerful. The mood maker of the group. If he had a girlfriend, he would be incredibly kind to her. There is a big gap between how he treats friends versus a partner.

Status: Doesn't have one yet... not yet... (I'm single!) Seating: Guest is directly in front of him. Kakeru is to his right. Aika is to his front-right.
